Answer: 11.9%

Step-by-step explanation:

Given : On a stretch of Interstate-89, car speed is a normally distributed variable with $\mu=69.1$ mph and $\sigma=3.3$ mph.

Let x be a random variable that represents the car speed.

Since , $z=\dfrac{x-\mu}{\sigma}$

z-score corresponds x = 73 , $z=\dfrac{73-69.1}{3.3}\approx1.18$

Required probability :

$\text{P-value }: P(x>73)=P(z>1.18)\\\\=1-P(z$

[using z-value table.]

Hence, the approximate percentage of cars are traveling faster than you = 11.9%

Answer:

6 inches

Step-by-step explanation:

The volume of a box can be calculated with the simple formula $l\cdot w\cdot h$ , where l represents length, w represents width, and h represents height. You know that $6\cdot 13\cdot h=468$ , so dividing both sides by 13 and 6 yields h=6 inches. Hope this helps!
